Application led. April 3, 1913. Serial No. 758,627.

To all fai/zoml' muy concern Be it known that l, Invlno Jansen, a citizen ot the l'lnited States, residing at Test lhfanch, in the county of Cedar and State ot' flown, have invented certain new and uset'ul Improvements in lliTater-lleaters, of which the ,totlowing is a speciticatii'ln.

My invention relates to water heaters and has particular reference to apparatus of this character adapted to be subn'lerged in the water held within a bath tub, tank or other receptacle, and to be removed therefrom after the water properly heated.

An important object of my invention is to provide a heater et the above mentioned character, which is compact, simple in construction, and cheap to manufacture.

A further object of the invention is to provide apparatus et the above mentioned character having novel means for heating the oil or other liquid :tuel before the same is supplied to the burner.

A further object of this invention is to provide novel means to hold the entire apparatus properly submerged in the water, and prevent the same from being upset therein.

@ther objects and advantages of this Ainvention will be apparent during the course of the following description.

ln the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout. the same, Figure l is a central vertical longitudinal sectional view through the entire apparatus, showing the same in its submerged condition, and, Fig. 2 is a plan view of the same.

ln the drawings, wherein for the purpose oit' illustration, l have shown a preferred embodiment oit my invention, the numeral 3 designates a tank or other receptacle, which is partially titled with water 4, to be heated. My heater comprises an opstanding body port-ion 5, having curved ends 6, which pref' erably carry handles 7. The body portion 5 is provided with a bottom 8, as shown.

The numerals 9 and l() designate transverse partit-ions or walls, disposed within the body portion 5 adjacent the inner ends of the curved ends G. These transverse partitions 9 and l() form with the curved ends 6, upstanding end passages 11 and 12 respectively, as shown.

The numeral 13 designates a horizontal oil or liquid fuel supply tank, which is formed of portions of the body portion 5,

portions of the, transverse partitionsI t) and llt), a bottom ll and a top li. .ihis top is provided with an opening which is normally closed b f a removable plugl lt, whereby oil maybe fed into the tank lll. ',the top lf3 has at one cud a stationary extension ,Ut closing the outlet passage l2, and atV its opposite end a pivoted perforated extension or lid lol', to be moved to open and closed posi-` tions. rlhe pivoted extension or lid lo" is perforated to allow ol" the inlet ot air into the inlet passage ll, but prevents the tree passage ot rain therein, when the apparatus is used out of doors.

The immoral lit designates a preferably downwardly swinging door, to normally close one end ot the burner chamber, mit pernlitting oit access thereto when opened, itor the purpose ot lighting the burner or the like.

onnected with the bottom 'lll ot' the tank 13, is an oil supply pipe l?, provided with a eut-oli' valve 15%, the stem l) oit which extends through an opening itorined in the partition 9 into the passage ll, as shown. Arranged below the pipe l? is a burner pipe 20, connected therewith, as shown. This burner pipe is horizontally ar1 'an;); `d and has its tree end closed by a cap Q1. The burner pipe is provided between its ends with a suitable number of pertorations Q9, to allow ot the escape ot the oil, which is ignited at this point. Below the burner pipe 2O is a horizontal partition or wall Q3, suitably attached at its ends to the train-- verse partitions t) and l0. This horizontal partition 23 is provided near its center with an upstianding tube 2l, the upper end of which is formed open and serves to support the burner pipe i2() and to supply air tothe same adjacent the pertorations Q2. The horizontal partition 23 is spaced :from the bottom 8 ot the body portion 5, lor providing a horizontal air passage 25, having communication with the upstanding air passage 1l through an opening 2G, as shown.

Disposed above the supply pipe is a horizontal partition or walt 27, suitably connected with the transverse partitions 9 and 10 and forming a chamber Q8. This chamber 2S has no communication with the upstanding passages 1l and 12 and is provided with a suitable number oi openings 29, whereby the cold water enters the chamber and is free to circulate into and out of the same.

titl

The products of combustion generated within the burner chamber 30, pass through an opening 31 and discharge into the upstanding passage 12. rlhis upstanding passage 12 is provided at its upper end with a stack 32, carried by the extension or section 15a, as shown.

l prefer to construct the body portion 5 and associated elements of sheet metal, owing to the fact that this material is very light and will readily transmit heat to the water.

rlhe numeral 33 designates a heavy weight, which weighs much more than the body por` tion 5 and elements contained therein. This weight has a lower convex surface, as shown at 34, and an upper horizontal surface which engages the bottom 8, and is suitably connected therewith. The function of this weight is to hold the entire apparatus properly submerged in the water and to provide a very low center of gravity, whereby the apparatus will always remain in its upright position and cannot be accidentally knocked over.

rlhe operation of the apparatus is as follows The tank 3 is partially filled with the water to be heated. The heater is then placed within the water, whereby Jthe same is submerged, as shown. y The valve 18 is now open, whereby the oil will escape through the perforations 22, at which point the oil is ig'- nited. W hen igniting the oil, the pivoted door 15C is swung to its open position, where` by the operator may insert his arm through the passage 11 into the burner chamber 30, to light the burner. The amount of the oil admitted to the burner is of course controlled by proper manipulation of the valve 18. Durinoa the operation of the apparatus, air is drawn downwardly through the passage 11 into the horizontal passage 25, and passes through the tube 24 to be supplied to the oil being burned at the perforations 22. Heated gases and products of combustion pass from the chamber 30 into the passage 12 and finally discharge through the stack 32. Attention is called to the fact that the oil passing through the supply pipe 17 is thoroughly heated before the same discharges through the perforations 22. rlhe oil within the tank 13 is slightly heated but this temperature is maintained comparatively low Ey the water circulating through the chamlt is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. Y

Having described my invention, l claim 1. ln apparatus of the character described, a main shell, heat generating means mounted therein, and a weight formed of a section of a sphere and attached to the lower end of the main shell and having its engaging sur- Y face smooth and regular whereby the weight will serve as a pivot upon which the apparatus may turn in all directions and as means for preventing the accidental tilting of the apparatus. f

2. In apparatus of the character described, a main shell adapted to be submerged in water while occupying a horizontal position; of means forming verticalinlet and outlet passages at the opposite ends of the main shell; means for dividing the main shell into an upper fuel holding chamber, and intermediate water circulating chamber, and a lower heating chamber, all of which are arranged horizontally and extend for the 'entire distance between the inlet and outlet passages; a burner mounted within the lower heating chamber; and a conduit connecting the burner with the upper fuel holding chamber. v

ln testimony whereof l aiiix my signature in presence of two witnesses. Y
